Marvel vs. Capcom is a series of fighting games created by Capcom in which characters created by Marvel Comics and Capcom's own characters appear together. While it was the first Vs. series involving Capcom, the Marvel brand exists to distinguish it from Capcom's other Vs. series with SNK (Capcom vs. SNK), and Tatsunoko Production (Tatsunoko vs. Capcom: Ultimate All-Stars).

The Marvel characters depicted in these games were often based on their incarnations in various 1990s animated series (particularly X-Men), and were often voiced by the same voice actors.
